2023 HYUNDAI SANTA FE Power Train Problems

The vehicle cannot pick up speed, and it is displaying the DTC- P1C2D03. This is similar to the issues that led to "Safety Recall 236 to repair a condition involving the 8-Speed Dual-Clutch Transmission (DCT) system" in earlier model years (till 2022) for certain Hyundai and Kia vehicles. NHTSA should issue a recall for 2023 model years also as Hyundai has not addressed this issue to the fullest extent in 2023 model years.

From a complete stop when pressing the accelerator, the vehicle does nothing. This can last 1 second or in longer episodes it can last 4-5 seconds. No lights on the dash. It’s random and happens sporadically. But when it’s bad, you have enough lag to count to 5 and turn on the hazards

There was a recall on the 21-22 santa fe for a issue with the transmission oil pump failure. I have a 23 which is not part of the recall but this is exactly what happened to me and now the transmission has failed completely with 68,000 miles

Front brake failure at 3k miles. Rotors warped so badly they failed to properly stop the vehicle. Vehicle shaking immensely Transmission failure at 11k miles. While vehicle is in Drive mode the transmission is stuck in first gear and will not shift. The tachometer was redlining at 6k I had to use the paddle shifters to get the transmission to shift. I was driving the vehicle as a manual transmission when I own an automatic.

Early March 2025 the vehicle was put car in park, got out of car to close yard gate, turned around to walk back to car but car was rolling forward and hit the flat bed trailer causing approximately $5000 in damage. It was put in park before getting out but jumped gear before getting back in. Another common problem is slamming the emergency brake on when attempting to drive. Was at a red lite left turn stop sign with foot on the brake. When the light turned green took foot off brake & put foot on accelerator to go forward, the car slammed the emergency brake on. This has happened approx 6 times in the 1-1/2 years of ownership.

Transmission caused vehicle to loose speed on grade posted speed 70mph I could not get over 35 Transmission stuck in 3 gear or would stay in 8th gear unable to gain speed almost got rear-ended vehicle has a 8 speed automatic transmission it will not shift properly loss of power account improper gear for speed

When accelerating from a stop, my car will not go over 20 mph. It just revs up like it’s not changing gears . I have to pull over and park it. It runs fine afterwards. This does not happen all the time. Usually it happens once a month. It’s been to the dealership 3 times. They drive it around the block and tell us that they can’t replicate the problem. Therefore, they don’t troubleshoot anything and return the car to me. I’m truly scared to drive it. I wrecked twice at a red light intersection.

The car has shut down unexpectedly for at least six times while driving at roads and highways. When this happens, engine stalls and nothing works and all alarms and check lights turn on and activated. Driver has to pull the car to the roadside which cannot be imagined when in a highway with all cars driving at 65-70mpH and the car suddenly slows down to stop. The other problem is that when the car is turned off and on again, all alarm and faults go away, and it can be driven again! It clears all safety and alarm checks and lights and behaves like nothing has happened. Car was bought on June2023. The first incident happened on Aug2023 and the next one on Sep2023. The next incidents on Feb2024, Sep2024, Nov2024 and the most recent on March 2025. The car has taken to the Sport Durst Hyundai dealership (Durham, NC) after incidents, however dealership did not perform any repairs in first four times claiming they could not duplicate the incident! (service reports attached for 3) After the third incident, we opened a case with Hyundai company trying to invoke the Lemon law, but our request did not go through despite all evidence we provided. Shamefully, their final suggestion to us was to sell the car! This was around March/Apr 2024. (Final decision letter attached) On fifth time, the driver did not shut down the car and towed it to the dealership while leaving electrical system on. They checked the car and claimed they found the cause and changed a part from car claiming it has been fixed. This was on Nov.2024. At the time we did not notice but, apparently that was a lie to make us quiet. The last time (sixth time) the same incident happened on [XXX]. The car was towed to dealership and is left there. We do have all screenshots from engine failures, although the dealership tried to wipe the history at some point.

The contact owns a 2023 Hyundai Santa Fe. The contact stated that while driving at an undisclosed speed, the transmission unexpectedly downshifted. There was no warning light illuminated. The vehicle was towed to the dealer but was not diagnosed or repaired. The contact stated that the failure reoccurred, and the vehicle was towed to the dealer. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure, and a case was opened. The approximate failure mileage was 55,917.

Mileage: 55,917

The contact owns a 2023 Hyundai Santa Fe. The contact stated while driving 45 MPH, the message "Shifter System Malfunction - Service Immediately" was displayed. The contact stated that the vehicle failed to shift into the park or reverse. The contact activated the parking brake and turned off the vehicle. The vehicle was towed to the dealer but was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 18,192.

Mileage: 18,192

While travelling at highway speed, attempted to accelerate to pass slow traffic. Rather than accelerating, the car hunted for a gear, and wouldn't shift properly. The car downshifted but engine would not go beyond 4000 RPM and speed remained the same. This has happened multiple times. By unexpectedly not accelerating, this created a risky situation by not allowing car to pass slower traffic as expected creating a potentially dangerous situation. (Video of one of the instances exists). No warning lamps, messages or symptoms occurred up to that point. Car was brought to dealer but since no codes were contained in the computer, they said there was no trouble found.

Automobile approached and stopped at stop sign. When accelerator pressed to continue, car remained in place, shuddering (as if transmission were slipping),and making significant noise. Car would not shift out of gear, nor move. Operator shut off car and then restarted car. Car started normally and was in park without shuddering. Expectations at busy intersection was that it was my turn to move and did not do so, creating doubt on what my car might do next. Traffic flow was briefly confused and some drivers honked and were unsure what they should do. This could have caused an accident with an impatient driver re-ending my car, or with others going through the intersection "out of turn" and unclear on my situation. No lights or other warnings were displayed before this incident. It has not re-ocurred. I brought into the dealer who had no other reports of this type of behavior.

Shuddering Issue with Current Vehicle: - Problem: Progressive shuddering during take-off, accelerating, slowing down, and braking uphill.

First- it has been reported to dealer at least twice when car was in for other service. They said they could not reproduce. When speeding back up from a stop on near stop, especially in a right turn, the engine will not accelerate. After a second or two it finally takes off. During this time, I fear getting hit by another vehicle, either from behind or to the side. It is very scary and puts me and my passengers at great risk! There was no warning indication at all. The date mentioned was the most recent time, but the issue has been happening since the car was brand new. Again, NO help from the dealer.

The contact owns a 2023 Hyundai Santa Fe. The contact stated while driving approximately 35 MPH and attempting to accelerate, the vehicle failed to respond or accelerate as intended. The vehicle started to decelerate and lost motive power. The contact steered the vehicle to the shoulder and parked the vehicle. After restarting the vehicle, the failure was self-corrected, and the vehicle operated normally. The contact stated that the failure reoccurred several months later. The vehicle was taken to the local dealer who was unable to duplicate the failure. The vehicle was not repaired. The failure mileage was 9,500.

Mileage: 9,500

I was driving the car moving in reverse to exit my driveway. I placed the car in Park and while the engine was running I exited the car. Upon exiting the car, the car immediately started to roll forward and crashed through my garage door leveling it to the ground. The car continued moving forward into the garage and came to a stop blocked by built in shelving at the back end of the garage. I could have been injured had the car started to roll while I was exiting the car or had some been in front of the car. No warning lamps or messages prior to the incident. The car has a safety feature if moving in Drive or Reverse and the driver door is opened the car shifts into Park. That feature failed. The car was inspected by a Hyundai dealer and claim no error codes found and dismissed any other information as provided in this report

There is an extreme amount of hesitation/delay from when you depress the accelerator and when the vehicle accelerates. I have had multiple incidences (both from a complete stop and while already moving) where I depress the accelerator and there is a concerning amount of lag time before the vehicle initiates movement. This has almost led to multiple accidents. This defect happens in all drive modes. This issue appears to have gotten worse over the time we have owned the vehicle. We did not notice this issue earlier on. We bought the vehicle brand new in Dec. 23.

Several times lately of extended crank. Saturday evening, car had been parked for 4 hours, did remote start and had extended crank of about 2 seconds. Car ran for about 3 minutes before we left. We left home and hit main road, tried to accelerate and vehicle seemed to go into limp mode. Would keep cutting the fuel out if tried to accelerate even above 40 mph. No check engine light came on. Put in neutral, could not get above about 3500 rpm. Vehicle was in smart mode where decides which mode to be in (normal, fuel economy or sport), when would try to accelerate it would try to change to sport as it knew power was not there. Was on a 6 lane highway and could not get up to speed. Finally was able to pull to side of road, shut engine off, waited a few seconds, restarted and issue went away, still no check engine light. I have contacted my local dealer, they said they have seen on another vehicle, was not sure of outcome, having service manager call me. Lots of complaints online forums of similar issues.

The contact owns a 2023 Hyundai Santa Fe. The contact stated while driving 50-65 MPH, the vehicle stalled and decelerated to a complete stop with several unknown warning lights flashing on the instrument panel. The vehicle was restarted and operated normally. The contact drove the vehicle to the dealer where several fault codes were reset. The contact continued to experience the failure and returned to the dealer where the dealer replaced the throttle assembly and later replaced a front camera with a hard code. However, the contact stated the failure persisted. The vehicle was with the dealer but was not repaired. The manufacturer was also notified of the failure and provided the contact with a case number and a case manager to assist with the failure. The approximate failure mileage was 1,700.

Mileage: 1,700

While parking my 2023 Hyundai Sante Fe, I hard pressed the break and pushed the Park button. The engine revved up and the vehicle took off instead of going into park; smashing into a building. The parking block was 6ft from the building. The engine accelerated to a high enough speed that it totaled the vehicle completely out. The engine code readings after the vehicle was towed to a repair shop was P0112 and P0114. The mechanic says that's the initial cause of the accident. The insurance reps are supposed to be following up on the mechanics diagnostics currently. There were no warning lights or anything on before the issue occurred as this was a brand new vehicle with only 8,000 miles on it.

While merging into the highway at approximately 49 to 52 mph, acceleration was applied to merge into the highway between moving vehicles. The vehicle responded by greatly increasing the rpm but not applying the power to the wheels. The engine revved up with very little acceleration. After 5 to 8 seconds, the power was finally transferred to the wheels and the vehicle sped up. The vehicle behind me had to apply the brakes since I basically cut them off. This was the second incident of this type.

This same scenario has happened 3 times since I purchased this vehicle - first event at mileage of 6273, 2nd event @ 7586 miles, and 3rd event @ 12,506 miles. All events were the same - while driving, dash board light start to flash and the vehicle looses all ability to accelerate. For each event, we have been able to coast out of traffic, turn the car off & restart. Once the car is restarted the acceleration works again, but the check engine light remains on along with an error code of P065312 Possible Power Train Issue. We have been very fortunate each time that we were on a road where we were able to coast out of traffic, but if this happened on a busy Interstate or Hwy traveling at high speeds we could have been rear-ended. The vehicle has been to the dealership twice for service and no problems have been found. The vehicle will be returned to the dealership tomorrow for 3rd service attempt.

My 2023 Hyundai Santa Fe have a recall to fix the trailer hitch, since that I notice some issues with the shifting with a loss of power while driving, my car is 15k miles and showed a check-engine light. I made an appointment for the dealership the next morning. After two days, I was told that the car needs a new transmission. After 3 days still waiting for the car to be fix.

My 2023 Hyundai Santa Fe Calligraphy with 14k miles showed a check-engine light. I had noticed some strange behavior in the shifting with a loss of power while driving at low gears. I made an appointment for the dealership the next morning. Was told today that the car needs a new transmission.

Vehicle has just over 4k Miles on it. Several times I tried to accelerate and while the engine RPMs would increase, the vehicle would not accelerate. Very dangerous when turning right on a red light and when merging into traffic. I came close to getting T-Boned on 4 occasions, and rear-ended on 3 occasions. This vehicle is not reliable and puts passenger lives in danger. Today the "Shifter System Malfunction-Service Immediately" warning came on and I was not able to shift into any gear and the vehicle put itself into neutral. Looking at the forums, this has been a problem throughout the Hyundia vehicle lineup for years with the DCT transmission. I don't understand how they can continue to sell these vehicles when there is a known safety issue with the DCT transmission. I have tried to contact Johnson Hyundia in Cary NC and left multiple messages with the service dept, but they have never returned my calls.

when I tried accelerate, the car jerked and then the transmission began to slip and I coasted to a stop. I cranked the car and slowly began to drive the car while it felt like the transmission was slipping. My first thought was that the transmission was low on fluid but later found that this is a sealed transmission. Luckily there was no traffic during this incident. There was no warnings lights or any warnings whatsoever.

I purchased a new 2023 Hyundai Santa Fe and on multiple occasions when trying to accelerate the vehicle has failed to go above 30 mph. I have put on about 6,000 miles. When I pull over and restart the car. The issue seems to resolve. This is quite dangerous when trying to get on the highway or accelerate to pass for myself, passengers in the car and others. The dealer has not been able to repeat the issue. No warning or error codes appear. After repeated returns to the dealer, the dealer has now refused to review the vehicle without a $200 charge to investigate. I am happy to make the vehicle available for inspection.

The contact owns a 2023 Hyundai Santa Fe. The contact stated that while driving at 75 MPH, the vehicle stalled and decelerated to 25 MPH as several warning lights flashed on the instrument panel. After multiple attempts, the contact managed to restart the vehicle and drove to her destination. The contact sustained severe emotional trauma due to the failure but did not seek medical attention. The contact drove the vehicle to the dealer where they informed her that the throttle body was defective and needed to be replaced. The manufacturer was also notified of the failure. The vehicle had yet to be repaired. The failure mileage was 2,689.

Mileage: 2,689

While driving under normal conditions with vehicle in Drive, transmission shifting into Neutral with no driver input or action and the engine remained running. Transmission indicator remained in Drive, and engine would rev, without forward propulsion. This occurred three times is close proximity, within 30 minute period. Each time, shutting down the vehicle, waiting approximately 5 minutes to restart, the vehicle would then shift into Drive normally and move under power. There were no warning messages or indicators prior to or during the three episodes. Dealer was unable to diagnosis any errors, even using GDS. If the vehicle had been moving at highway speed or on a more congested roadway, this could have posed a significant safety risk to the occupants and any nearby vehicles, as the driver may have not been able to safely pull off the roadway when the vehicle lost propulsion (shifted to neutral).

Car was purchased January 21st had 3000 mile on it when service was needed for these issues. On march 23rd as I started driving my car wouldn't go above 30 mph, when pressing on the gas pedal the car wouldn't accelerate, the rpm gage would go to 4 but engine wouldn't make noise car wouldn't speed up. I put the car in park and back in drive with no improvement. I pulled off at a gas station restarted the car and it was fine. During this time the auto on off button was orange on the cluster which I had never seen it that color before. Was looked at by the dealer but wasn't reproducible. Not sure the cause, but safety was in jeopardy due to not being able to go with speed of traffic. Also a couple weeks after purchase brakes began to squeal, took car to dealer on march 28th was told brake pads were sanded and cleaned, upon leaving dealer brakes continued to squeal, car is now back at dealer, supposedly needing front rotors and pads replaced. Dealer won't drive car until rotors replaced. Safety was in jeopardy cause of possible brake failure and resulting accident.

2023 Hyundia Santa Fe bought brand new from the dealership. During the course of the last month and a half the vehicle has done things with unknown origin. The panic alarm will randomly go off when the vehicle is turned off, no one is in it, or even near it. By locking the vehicle with the remote, the alarm will tend to go off about 20-30 seconds after the vehicle is locked and will sometimes not stop until the vehicle is restarted. The transmission will shift very roughly almost to the point that it feels like you are driving a manual transmission vehicle. The transmission lags in gears between 60-70 miles per hour and you feel a very rough back and forth shifting with in the transmission. Next the emergency break would engaging and then not releasing or reengaging when parked on a hill, flat service or anywhere. The break light on the dash would light up, blink, then it would go off, making it unknown if the emergency break was acting engaged or not. The dealership I purchased it from did replace the EMS module along with breaks and rotors on the vehicle. The auto shut off or the idle shut off will also randomly work, and not work. it will cut on and off even if the button is pressed to shut it off or prevent it from coming on. Now the air condition, along with the heat and heated seats has started to not work, randomly cut on, will not cut off etc. While driving i have had the heated seats turn on, along with the heat and not go off, nothing would cut off until the vehicle was physically turned off and restarted. No codes have ever been displayed or found by the dealership.

Stopped at left turn lane light. Light turns green and vehicle engine revolutions increase as I press on gas pedal but car does not move. Cars behind me lean on their horns and take evasive maneuvers to go around me. Car finally goes very slowly and transmission disengages in middle of left turn leaving vehicle in middle of intersection with oncoming traffic. Luckily everyone stopped and vehicle very slowly moved through the intersection to side of road. Vehicle is brand new and in my possession less than 48 hours. Vehicle is at dealership for troubleshooting.
